The simulation results show that secondary cracks initiate at the grain boundary region near the primary crack due to its induction. Additionally, they can also initiate at multiple locations in the high-angle grain boundary regions far from the primary crack. This occurs due to elastic stress concentration and plastic strain localization in these regions. Then secondary cracks mainly propagate along prior austenite grain boundary areas. The tensile stress on both sides of the crack tip is the main driving force for crack initiation and propagation. As the external loading increases, the stress at the crack tip gradually transitions into compressive stress, ultimately leading to the closure of the crack in the grain boundary regions. More importantly, these propagation paths of secondary cracks are consistent with the experimental results. Compared with intracrystalline defects, grain boundary defects are more likely to induce crack initiation and propagation.

However, controlling the TRIP effect poses a great challenge due to the difficulties in manipulating the stability of reverted austenite (RA). In this work, through introducing nano-precipitates into the RA, we achieved a significant improvement in the work-hardening ability for MSSs. The role of the RA decorated and not decorated by nano-precipitates (RADP and RANDP, respectively) was carefully investigated. The precipitation of Ni<sub>3</sub>(Ti, Mo) and Mo-rich phases within RA causes a low stacking fault energy (SFE) in the RADP compared to the RANDP. In the initial stage of deformation, the RADP is susceptible to the TRIP effect due to the low SFE, which can effectively relieve stresses. Upon further deformation, the nano-precipitates within the RA can block the movement of the 1/6 < 112> Shockley partial dislocations and delay the transformation, thus improving the stability of the RA. This results in a sustainable absorption of stresses and delays the initiation and propagation of cracks. Moreover, the nano-precipitates in the matrix provide a significant increase in strength. Consequently, an excellent combination of high strength, ductility, and work-hardening ability was obtained in the MSSs. The newly developed MSS demonstrates a yield strength of 1790 ± 24 MPa, a tensile strength of 2140 ± 32 MPa, a uniform elongation of 9.5 ± 1.3 % and a total elongation of 16.4 ± 1.1 %.

Consequently, this study presents a systematic examination of the impact of direct ageing on microstructure evolution in an LPBF Al‒Ni‒Sc‒Zr alloy, analysing associated changes in strength and plasticity. The optimal ageing parameters for strength and plasticity are determined. The results demonstrate that the reduction in strength resulting from cell decomposition can be offset by the strengthening provided by nanoparticles formed due to cell wall spheroidisation and additional supersaturated solute precipitation, achieving excellent yield strength. Furthermore, the transformation of cells into nanoparticles significantly enhances the plasticity by increasing non-uniform strain, which is not well explained by the conventional work hardening theory. A detailed investigation suggests that direct ageing can alleviate dislocation pile-up and strain localisation around cell walls, and reduce the tendency for crack propagation along melt pool boundaries, resulting in a significant increase in non-uniform strain and ultimately, excellent tensile plasticity.
